A piece of rope walks into a bar and orders a drink. The bartender says, "I'm sorry, but we don't serve pieces of rope." So the piece of rope goes back outside. He tousles one end of himself, and then ties himself in the middle. Then he goes back into the bar and orders a drink. The bartender says, "Aren't you that same piece of rope that was just in here?" The piece of rope says, "I'm a frayed knot."
